Definitions
- the invention relates to a device for ventilation, a breathing gas pump, a connecting hose, a Respiratory mask and an expiratory element and has when in the area of the breathing gas pump halternden Device housing a device filter for restraint Air pollution is arranged, as well as in the Breathing gas pump has a control such that both within inspiration phases as well as within Exhalation phases a nasal continuous positive Airway pressure is provided.
- Such devices are typically used when sleep-related in patients Respiratory disorders need to be treated.
- a fundamental problem in the implementation of Continuous breathing is that the body of the patient Heat and moisture are removed. typically, is therefore in device technology terms a separate one in addition to the actual ventilator Humidifier and air heater used.
- Known is for example the use of cold humidifiers, in which the air intended for breathing over a Water surface rubs off and gets wet accumulates.
- the breathing air is not warmed up and the extent of attainable moisture accumulation is limited.
- humidifiers are used, the can be regulated and heated to a higher To ensure moisture content. Depending on one however, it is possible to that thereby a 100% saturation of the breath with Moisture is achieved and that thereby in the area the connecting tube condensation takes place. Also can not be excluded that a permanent over-humidification of the respiratory tract is caused which interferes with a function of the cilia or even blocked.
- HME filters used in emergency respirations be exhaled by the patient moisture and heat to withhold and a passage of germs and prevent other microorganisms.
- such filters have the disadvantage on that at a gas flow a relatively high Pressure drop occurs, which is a material technically in is a larger range of dispersion and the above in addition, depending on the respective conditions of use varied.
- An immediate use of this Filter in the area of continuous ventilation of sleep-related Respiratory disorders while providing a continuous positive airway pressure is therefore not possible.
- EP-A 0 549 299 a device for ventilation described in connection with the application CPAP therapy in the area of the air supply a respirator a filter and a humidifier are arranged.
- DE-C 43 38 813 a device for use described in the field of CPAP therapy, wherein the device with a heated and adjustable Humidifier is provided.
- From US-A-5,460,172 is an HME filter for applications known in the context of tracheotonomy.
- the geometric design of the HME is provided on the Use case adapted.
- the object of the present invention is a device of the type mentioned in the opening paragraph, that provided improved ventilation characteristics become.
- This object is achieved in that in the area of the respiratory mask and the exhalation element at least one filter for the retention of heat and moisture is arranged, that the filter a Flow resistance of less than 20 mbar at one Flow of 60 l / min and that the filter material is arranged interchangeably within the filter.
- Another object of the present invention is a Specify method of the type mentioned in the introduction that the physiological quality of the breathing gas is improved.
- This object is achieved in that in close proximity to the respiratory mask from the respiratory mask outflowing respiratory gas is filtered in such a way that portions of moisture and heat retained and that the filtering is done in such a way that on the filter for the retention of moisture and Heat at a pressure difference of less than 20 mbar a flow of 60 l / min is generated.
- the preparation of the respiratory gas according to the invention also supports both mobile applicability as well as low device prices as well as low Operating cost.
- a tightly tolerated maintenance of the nasal continuous positive airway pressure supported in particular by the fact that Flow resistance less than 2 mbar at one Flow of 60 l / min.
- a compact structure is supported by the fact that the Filter is designed as part of the respiratory mask.
- a use of standardized components is supported by the fact that the filter between the Respiratory mask and the expiratory element arranged is.
- the filter as part of the Exhalation element is formed.
- the filter material inside the filter is arranged interchangeably.
- Filter material formed of a plastic wadding is.
- the filter material contains salt components.
- the salt components are formed hygroscopic.
- the restraint effect can also be characterized be supported that the filter material electrets to Generation of a permanent electric field contains.
- Filter material at least partially out Polypropylene is formed.
- the filter material at least partially made of polyurethane is.
- Another way to realize the Filtering properties is that in the range of Filters at least one membrane is arranged.
- the filter material a foamed substance is formed.
- Filter material of a fibrous material is trained.
- a particularly lightweight and easily replaceable Construction is provided by the Filter material at least partially made of paper is trained.
- a compact construction is also supported by that the filter in the area of the connecting hose is arranged.
- Fig. 1 shows the basic structure of a Apparatus for ventilation with simultaneous generation a nasal continuous positive Airway pressure.
- a device housing (1) with control panel (2) and display (3) is in one Device interior arranged a breathing gas pump.
- Over a Coupling (4) becomes a connecting hose (5) connected.
- the connecting hose (5) runs an additional Druckmeßschlauch (6), the via a pressure inlet port (7) with the Device housing (1) is connectable.
- the device housing (1) has a Interface (8).
- Exhalation element (9) In the area of the device housing (1) facing away Extension of the connecting tube (5) is a Exhalation element (9) arranged.
- FIG. 1 also shows a respiratory mask (10), which is designed as a nasal mask.
- a fixation in the The area of a patient's head can be over Hood (11) take place.
- Hood (11) take place in the area of her Connecting hose (5) facing extension points the respiratory mask (10) a connection piece (12).
- a filter (13) for restraint arranged by heat and humidity.
- the filter (13) has a filter housing (14) in the filter material (15) is arranged.
- the filter housing (14) from a Upper housing part (16) and a lower housing part (17) form, reversibly connected and can be separated from each other.
- filter materials for example, fibers or open-pore foams made of polypropylene or polyurethane be used. It is also possible to appropriate To use membranes. A moisture retention can by using hygroscopic salts be improved. It is also possible to electrete to use, the material due to a permanent provide electric field.
- the use of the filter (13) prevents that exhaled moisture as well as with the respiratory gas dissipated heat to the area of Exhalation element (9) and through this in to enter an environment. The heat and the humidity Rather, in the region of the filter (13) at a Exhalation process attached and stream at one Inhalation process through the respiratory mask (10) back to the patient.
- Fig. 2 shows an embodiment in which the filter (13) is formed as part of the respiratory mask (10).
- FIG. 13 A further variant for the realization is shown in FIG. 13 shown.
- the filter (13) as part of the Exhalation element (9) realized. Also this can a compact embodiment with a low number of parts be achieved.
- Fig. 4 shows in a cross section a possible Structure for the filter (13). It is special recognizable by the filter (13) and through the Filter material (15) through the Druckmeßschlauch (6) is looped through. This makes it possible immediately in the area of the respiratory mask (10) capture current pressure and the device housing (10) supply with the controls provided there. This will help maintain the nasal continuous positive airway pressure within supported by a small tolerance interval. Basically, it is at a suitable Dimensioning of the filters (13) in terms of Flow resistance but also possible, the Pressure measurement in the area of the device housing (1), or between the filter (13) and the Breathing gas pump to perform. Such a measurement is particularly useful when the flow resistance of the filter (13) at a flow of 60 l / min is at most 2 mbar.
- a Coarse filter for the retention of impurities and Germinating as well as the required electrical and arranged electronic components.
